To all 'whom 'it may concern.:

it known that l', @LA A.. ANnEBsoN,' a citizen of the United States,residing at Grand ftapids, in the county .of'Kcnt and State of Michigan,have "invented certain new and nsefulflrnprovements in Benchlllochs,ofWl'illb/the following is a specication.

"My invention relates to improvements in bench blocks for use on cabinetbenches, carpenters benches, etc., and its Objectis to de a cheaplyconstructed bench blockv .l with which the danger of dulling ning' aplane bit, should it come in contact with the surface of the block whenplaning lumber, is practically eliminated.

l attain this object by the construction and assembling of metals shownin the accompanying drawing, in which Figure 1 is a plan of the'completed block; Fig. 2 is a longitudinal section of the same on theline of Fig. l showing1 the layers of metal and the manner of assemblingthem to in'u ill a perfectly safe and seourenianner of uniting the twometals in the-construction of the block; Fig. 3 is a transverse sectionof the saine on the line l l of F 1;and' Fi f. is a plan of the base, orsupporting f of the bloei; to which thssofter metal tired. Sin larnumerals refer to similar parte #hout the several views shown in thedran lia-'the construction of this block l make a base or snnnortingelement '2, of cast iron, east stce., V- other suitable metal of Sullil'to safely support the softer ,le the coatingl of soft metal 1 ...j beapplied to any form ofmetal bench inoclc, for convenience l have appliedit to the bench blo-cli patented tof/nie April 6, i916, by LettersPatenthT l, 134,937, the only chanpge in the block shown in said patentbeing in the forming of the upper surface thereof. ln the former patentthis was shown as a plain cast iron block. ln this case the edges of theblock are made flaring and the' eenter'of the upper surface is remoyed'to forni the dovetailcd rim or border to 5. l, also, drill, or formflaring holes, 3, for the purpose of strengthening the center of thesofter metal.

Specification ofLetters Eatent. Application lled Julie 26, 1916. SerialNo. 105,074.

retenant ling, a reir.

When the clore has been properly prepared it is placed in a properlyformed mold, vas 7, as indicated in F ig. l, and the mold, around thecore, is filled with some soft metal, preferably lead, solder or verysoft Babbitt metal, previously melted and properly poured into the mold.

It will be readily understood that with the softer metal properlyprepared and poured into the mold, over and around the core or base 2,and conformingr closely to the dovetailed edges, and the flaring holes 3of the core, as at 5 and 6, the softer metal becomes practicallycoherent with the harder metal, especially if the harder metal has beenproperly prepared and a flux used that will cause the softer metal, inits melted state, to adhere to the surface of the harder metal, as bysoldering. The last mentioned condition is very desirable in theconstruction of these blocks, though it is not absolutely necessary.

It is not material where the holes 3, 3, in the base or core 2, arelocated, as they are used only to strengthen the soft metal cap l,though l prefer to have them near the front edge of the block, asindicated in Figs. 2 and d, as by this means they act more directly tostrengthen 'the soft metal at the edge upon which the greatest strain isexercised. However, I frequently place these holes in practically theposition shown in F ig. 3, especially if making the blocks so narrow, incross section, as to preclude the possibility' of locating them forwardof the standard l, as in Figs. 2 and Las hereinbefore suggested.

What Iclaim as new, and desire to secure by Letters Patent ofthe UnitedStates, is

ln a bench block, a broad metal base forming a. thin web havingdownwardly and outwardly Haring holes therethrough, a dove- 'tailedborder integral with and extending upward vfrom the base, aAsupporting,r stem integral with and extending downward from the base,and a soft metal covering around, within and upward from the base andthe dovetailed border and through the openings in the base.l Signed atGrand Rapids, Michigan, June es, 191e.
